Data collection

Enrollment in DD2 consists of a questionnaire (with a few questions for the patient and a part to be filled out by the enroller) and the collection of a urine sample and a blood sample. All individuals older than 18 years of age diagnosed with diabetes within the last 2 years are eligible for inclusion in DD2.

The individual can either sign up online (and then be contacted) or be approached by the practice personnel (e.g., during a regular diabetes check-up). The individual will receive an e-mail with a link to WebPatient, where a few questions should be filled out before the questionnaire will be sent to the practice. Hereafter, a DD2 examination will take place, where additional questions will be answered (e.g., diabetes debut date assessed by the enroller) along with a physical examination (weight, hip and waist circumference, resting heart rate, …). The examination also involves a urine sample (morning urine) and a blood sample (fasting).

Enrollment can either take place in the practice (GP) or in the outpatient clinic. Registration is also possible for individuals without internet access.
